"If you create the file, it will return &true; even if you then delete
the file". Are you sure?
<?php
var_dump(file_exists('temp.txt'));
touch('temp.txt');
var_dump(file_exists('temp.txt'));
unlink('temp.txt');
var_dump(file_exists('temp.txt'));
?>
Outputs:
bool(false)
bool(true)
bool(false)
for me, on PHP 4.3.4RC1 (cgi) (yeah I know, I need to upgrade :P).
"PHP don't cache information", should also be "PHP doesn't cache
information", or "PHP does not cache information".
